摘　　要：平面应变压缩实验机对X70管线钢在平面应变压缩条件下的再结晶行为进行了研究.研究表明在实验条件下,本钢种只发生动态回复,不发生动态再结晶.同时探索出一种新的管线钢原奥氏体晶界腐蚀方法.In this paper, recrystallization behavior of X70 pipeline steels is studied by using the plan strain compression machine in the plane strain compression conditions. It is observed only the dynamic recovery occurred but no dynamic recrystallization occurs in the experimental condition. A new method for showing the prior austenite crystal boundary corrosion, of pipeline steel has been also supposed.
